Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ventilating water draining structure when starting to stretch the first stage of a dry wall material used as an exterior material.
[0002]
[Prior art]
Conventionally, as a method of forming a ventilation structure using a dry-type wall material, as shown in FIG. 11 , a waterproof sheet D made of a windproof and moisture-permeable sheet is applied on a housing C (a wooden base, a steel base, etc.) A drainage H is constructed between the aeration trunk edge F and the foundation γ of the wall base α on which the ventilation trunk edge F is formed via the fixture β, and then the starter I is constructed with the fixture β. It was constructed by inserting the lower end of the dry wall material B. Of course, in this case, a gap a is formed between the foundation γ and the drainage H, and ventilation is performed through the gap a. Further, a waterproof sheet D such as asphalt felt may be further formed on the ventilator rim F from the fixing part of the drainer H, or an insect repellent sheet made of stainless mesh or the like may be formed so as to cover the gap a.
[0003]
[Problems to be solved by the invention]
However, it is necessary to take dimensions in the above-described drainage, and the work of forming the gap a is troublesome and takes time for construction. Moreover, since the dimension of the space | gap a is important for determining air flow, it had to be constructed with a certain dimension. Furthermore, if the size of the gap a is too large, insects (ants, bees, etc.), small birds, dust, etc. may invade from the gap a, and there is a risk of blocking the air passage or destroying the enclosure. It was. Of course, if the formation of the air gap a is insufficient, the performance of the air passage cannot be sufficiently exerted, and moisture remains in the inside of the housing, which causes corrosion of the housing, mold, and mites. In addition, in houses such as Hokkaido, where the foundation is high for snow measures, the back side of the ventilating drainage is completely visible from the bottom, which has a big problem with aesthetics.
